Abstract

Gasdichte Rohrverbindung für Futter- und/oder Steigrohre innerhalb eines Bohrlochs, bestehend aus einem mit Außengewinde versehenen Zapfenteil und einem mit dazu passendem Innengewinde versehen Muffen­ teil, wobei im Gewindebereich des Muffen- und/oder Zapfenteiles eine Nut zur Aufnahme eines verformbaren Dichtungsringes existiert, der bei verschraubter Rohrverbindung durch das Nutgrundprofil des Muffen- und/oder Zapfenteiles und das Gewindeprofil des jeweils anderen Verbindungsteiles begrenzt und geformt wird und bei welcher die von Nutgrundprofil des Muffen- und/oder Zapfenteiles und Gewindeprofil des jeweils anderen Verbindungsteiles umschlossene Querschnittsfläche über den Nutverlauf konstant gehalten und gleich oder größer als die Querschnittsfläche des verformbaren Dichtungsringes vor der Verschrau­ bung ist. Gas-tight pipe connection for casing and / or riser pipes inside a borehole consisting of an externally threaded one Spigot part and a socket provided with a matching internal thread part, one in the threaded area of the sleeve and / or pin part Groove for receiving a deformable sealing ring that exists at screwed pipe connection through the groove base profile of the socket and / or pin part and the thread profile of the other Connection part is limited and shaped and in which the of Groove base profile of the socket and / or pin part and thread profile of the each other connecting part enclosed cross-sectional area the groove course kept constant and equal to or larger than that Cross-sectional area of the deformable sealing ring before screwing exercise is.
